A. First of the Invention Example

a) applicator

As can be seen in FIGS. 1 to 4, the applicator 1 has a protective tube 2 extending in the longitudinal direction X between the first and second ends 3, 4. More specifically, the protective tube 2 may be generally cylindrical in shape of the central axis (X). The second end 4 is open.

This protective tube 2 may for example be made of plastic and may be covered in a prominent outer area (meaning an area near the second end 4), possibly by a decorative metal ferrule.

Protective tube (2)

For example a cup 7 made of plastic,

An interchangeable cartridge 6 with a stick 8 of material is included, the stick of lipstick being used as an example in all figures.

The stick 8 of material is generally made of a solid or paste-like material that can be shaped into a stick that remains stable over time at room temperature. Solid or paste-like materials of this type generally comprise waxes or wax mixtures and are deposited by contact with the surface during use. Solid or paste-like material is also understood to mean a material that can penetrate a hard object without losing its integrity when shaped into a predetermined form such as a stick.

The stick 8 of material is a fabric which is close to the near end 9 firmly attached to the cup 7 and the second end 4 of the protective tube and is formed to withdraw the protective tube 2 by the second end 4. It extends along the longitudinal direction X between (10).

In the example shown in the figure, the cup 7 defines a predetermined internal volume into which the proximal end 9 of the stick of material is inserted. More specifically, in this example, the cup 7 may have a side wall 12 having a lower end 11 and an overall cylindrical shape centered on the X axis, for example. This side wall 12 extends from the lower end 11 to the free end 13 in the direction of the distal end 10 of the stick of material.

In the present invention, to facilitate the extraction of the cartridge 6 of material when the stick 8 of material is at the end of its service life, the cup 7 projects radially inwards and has a stick of material inside the cup ( An inner lip is provided which can cooperate with an external extraction member penetrated by a stick of material to cover the used cartridge 6 but to replace the used cartridge 6 and replace it with a new cartridge.

In the first embodiment of the invention, the inner lip of the cup consists of an annular rib 14 arranged inside the side wall 12 near the free end 13. In more detail, as shown in FIG. 2A, the rib 14 may have an inclined surface 15 and a shoulder 16 if applicable, the inclined surface having a lower end 11 substantially perpendicular to the central axis X. FIG. It extends downwardly and radially inward with the shoulder 16 oriented towards).

As shown in Figs. 1 and 2, the applicator 1 is further

A retracted position (Fig. 2) in which the stick 8 is fully received in the protective tube 2,

A control device 17 for moving the stick of material between the use position (Fig. 1) where the stick 8 protrudes from the second end 4 of the protective tube 2;

In the example shown in the figure, the control device 17 includes a base 18 that forms the bottom of the applicator. The base 18 extends along the central axis X from the lower end 19 and the lower end 19 to allow the applicator 1 to be placed on a horizontal surface and is protected near the first end 3 of the protective tube. It has a side wall 20 surrounding the bottom of the tube 2.

The upper part of the sidewall 20 of the base 18 may be a thin portion 21 (possibly 22) (Fig. 1) in which the protective cap may cover the protective tube 2 when the stick 8 of the material is in the retracted position. ).

The base 18 may be assembled to rotate about the protective tube 2 about the central axis X to control the sliding of the stick 8 of material between the retracted position and the use position. As shown in Figures 2 and 3, the control device 17 is possibly

A screw 23 extending longitudinally along the axis X and integrally attached to the sliding element 24 which slides along the axis X in the protective tube 2,

A nut 25 fixed to the screw 23 and attached to the base 18 to rotate with the base 23.

In the specific example shown in FIG. 2 or 3, the screw 23 can be made of the same plastic piece as the sliding element 24 and the nut 25 can also be made of plastic.

Screw 23

Two flat opposed surfaces 26 running parallel to each other and to the axis X (see FIGS. 2 and 4),

As can be seen in FIG. 3, it may be in the form of a hollow zone with two sides 27 in the form of a circle which are diagonally opposite to each other and centered on the axis X connected to the flat surface 26. The circumferentially shaped side 27 has an outer thread 28 which meshes with the inner thread 29 to the nut 25 (see FIGS. 3 and 4).

The screw 23 extends from the sliding element 24 to the lower end 19 of the base 20 and may be formed in the same manner as the protective tube 2 made of plastic, the first and second ends of the protective tube ( In the intermediate position between 3 and 4, it passes through the opening 30 in the transverse wall 31 which extends radially inward from this protective tube. As shown in FIG. 4, the opening 30 can have a shape that is substantially complementary to the outer shape of the screw 23, thereby preventing the screw 23 from rotating around the axis X (screw 23 Two flat surfaces 26 in sliding contact with the two opposing straight edges of the opening 30), while the screw 23 has a sliding element 24 and the protective tube 2 along the axis X. Let's move inward parallel.

The movement of the screw 23 into the protective tube 2

-Down (meaning towards the base 18) by the sliding element 24 stopped by the transverse wall 31,

Limited by upward contact (meaning towards the second end of the protective tube 2) by the contact of the two elastic tabs 32 against the lateral wall 30.

These elastic tabs 32 may be molded in the same part as the screw 23, for example near the free end 33 of the screw 23, wherein the elastic tabs 32 are provided with a protective tube ( If it is installed in 2) can be formed to pass through the opening 30 in the transverse wall 31 by elastically deformed. To this end, the elastic tabs 32 can be deformed radially inward and each elastic tab is inclined radially outwardly obliquely upwardly from one of the flat sidewalls 26 of the screw, if necessary. And an upper stop surface 32b extending substantially perpendicular to axis X (see FIG. 2).

The sliding element 24 may itself be, for example, in the form of a simple plate extending perpendicular to the axis X or in the form of a dish open towards the second end 4 of the protective tube, or any other form. have. This sliding element 24 is equipped with a central opening 34 in which the elastic lug 35 can be fixed in place in the form of a single piece below the bottom 11 of the cup 7 described above in the examples considered herein. do. This elastic lug 35 has a substantially cylindrical symmetry centered on the axis X, for example, at its free end the lip 37 protrudes radially outward and is fixed in place in the opening 34. It may have a side wall (36) formed to hold the cup (7) detachably.

Finally, the nut 25 described above may have a lower portion 38 which may or may not be grooved, for example, and is forced inside the complementary arrangement arranged on the base 20. The lower portion 38 is annular in shape and surrounds the screw 23 without interfering with the screw. The lower part 38 extends towards the transverse wall 30 of the protective tube by an intermediate annulus 39 which is not threaded by itself and then an upper part 40 which is equipped with the internal thread 29 described above.

By means of the control device 17, the base 20 slides the sliding element 24 and the cartridge 6 of the material in such a way that the stick of material 8 protrudes from the protective tube 2 or retracts into the protective tube. Thereby rotating about the protective tube 2 around the axis X.

Of course, the particular control device described above is provided only as an example. Other control devices, in particular control devices with grooves in portions concentrically arranged with the stick 8 of the material, as is well known in the art, can also be used to control the movement of the stick of the material.

b) refill

5 to 8 show an example of the refill 41 used to change the cartridge 6 of the material in the application device 1 described above.

The refill 41 has a casing 42 made of plastic, for example, which casing contains a new cartridge 6 of the same material as the cartridge 6 described above with respect to the applicator 1. ) (See FIG. 6).

The casing 42 may possibly have a substantially parallel outer shape and may be elongate extending longitudinally along the central axis X '. The refill housing 43 may be in the form of a cylinder centered on the axis X '.

The casing 42 may have an annular inner sidewall 44 that delimits the refill housing 43, which refill housing has a central axis X ′ between the first end 45 and the second end 46. Stretched along. The first end 45 of the refill housing 43 may be closed by a diaphragm 47 formed in the same portion as the side wall 44 of the refill casing, for example. The second end 46 of the refill housing may be temporarily closed by a removable protective membrane 48, which may be heat sealed or glued, for example to a cross section of the side wall 43 (see FIGS. 6 and 8). .

As shown in FIG. 6, a new cartridge 6 of material is disposed in the refill housing 43, and the lower end 11 of the cup is near the second end 46 of the refill housing, the far end of the stick of material. 10 is near the first end 45 of the refill housing.

The cartridge 6 is held in place in the refill housing by inserting the cup 7 into the second end 46 of the refill housing, the refill housing being pressed against the cup in the axial direction X '. It has a shoulder 49 directed towards the two ends 46. Thus, the shoulder 49 is used in the axial direction X 'while placing the new cartridge 6 in the applicator 1 after the used cartridge 6 has been removed from the applicator as described below. 7) can be pressurized.

More specifically, in the example contemplated herein, the refill housing 43 has a cup holding means, which means is an annular inner wall 50 of substantially overall cylindrical shape centered on the central axis X '. , Which may be molded into the same plastic piece as the casing 42 and extend along the central axis X ′ from the diaphragm 47 to a free end 51 located near the second end 46 of the refill housing.

The annular inner wall 50 may have a terminal portion 52 having an enlarged inner diameter that borders the shoulder 49 in the vicinity of the free end 51. The side wall 12 of the cup of the new cartridge 6 is inserted into this terminal portion 52, and the free end 13 of this side wall is pressed against the shoulder 49.

The annular inner wall 50 may have an annular inner lip 53 that contacts the side wall 12 of the cup near the free end and allows smooth insertion of the cup into the annular inner wall 50.

Casing 42 of the refill may further include a cap 54 to temporarily close the shoulder end 46 of the refill housing.

This cap 54 can possibly be pivotally mounted to the side wall 44 of the casing. For this purpose, the cap 54, for example

A central portion 55 for covering the second end 46 of the refill housing,

It may be U-shaped including two arms 56 assembled to pivot on two respective pivots 57 at two opposite sides of the side wall 44 of the casing 42.

Arm 57 is additionally

A closed position in which the central portion 56 of the cap presses against the facing face of the casing to block the second end 46 of the refill housing 43, and

-Can be assembled to slide with respect to the side wall 44 of the casing between the release positions at which the cap is moved away from the second end 46 of the refill housing, whereby the center portion 55 of the cap is refilled It is sufficiently far from the second end 46 of 43 so that the cap does not pivot and interfere with the second end 46 of the refill housing.

In the particular example shown, the pivots 57 are each formed on the inner side 58 of the arm 56 (see FIGS. 6-8) and these pivots 57 face the sides of the side wall 44 facing the arm 56. It is assembled to slide in two respective grooves 59 which are arranged at. Each of the grooves 59 is open toward the corresponding arm 56 and extends along the central axis X 'side by side in the longitudinal direction. Advantageously, each groove 59 has at least one narrow portion 61 delimiting at least one retaining slot 60 at the end of the groove 59 opposite the second end 46 of the refill housing 43. ) May be provided. This retaining slot 60 accommodates the pivot 57 when the cap 54 is in the closed position, as shown in FIGS. 6-8, and then allows the pivot 57 to slide unintentionally. prevent.

Each groove 59 also has a second narrow portion 61 defining second retaining slots 60 for holding the pivots 57 in place when the user slides the cap 54 to the release position at the opposite end. ) Narrowing portion 61 is not sufficiently pronounced to allow the user to slide and deflect cap 54 elastically to deform and accept the passage of pivot 57.

As shown in FIG. 6, the refill casing 42 may be further provided with an extraction housing 62 that is circumferentially shaped and may be centered on the axis X ′ and open to the opposite side of the refill housing 43. have. This extraction housing 62 can extend along the axis X 'from the diaphragm 47 to the open end 63, and the stick 8 of material in the used refill 6 of the applicator 1 It may include at least one extraction member 64 formed to penetrate the remaining. This extraction member 64 has an outer lip 66 formed to cooperate with the inner lip 14 of the cup of the cartridge used to hold the inner lip and to allow extraction of the cartridge used from the applicator.

In the first embodiment of the present invention, the extraction member is at least extending along the axis X 'from the diaphragm 57 to the free end 65 having the outer lip 66 toward the open end 63 of the extraction housing. With one wall, the outer lip 66 is formed to hold under the inner lip 14 of the cup of the cartridge used. More specifically, the outer lip 66 of the extraction member 64 may have a shoulder 68 that is directed towards the diaphragm 57 and formed to hold under the inner lip 14 of the cup of the cartridge used. Advantageously, the outer lip 66 may have an inclined surface 67 extending radially outwardly in the diaphragm 47 direction to the shoulder 68 which may be perpendicular to the axis X '.

In the example shown in the figure, the extraction member 64 is in the form of a ferrule substantially cylindrical in shape and centered on the axis X ', but this ferrule can be replaced by a plurality of tabs each having an outer lip 66, for example. have.

The just described refill 41 can be used as follows.

When the stick 8 of the material of the applicator 1 reaches the end of its service life as shown in FIG. 9, the second end 4 of the protective tube 2 of the applicator 1 is refilled and casing. It is fitted to the extraction housing 62 of 41. Advantageously, the inner diameter of the extraction housing 62 is substantially the same as the outer diameter of the metal ferrule 5 (or the outer diameter of the protective tube 2 if it does not have such a ferrule 5). By insertion the central axis X 'of the refill 41 is aligned with the central axis X of the applicator 1.

During this movement, when the user applies pressure to the refill 41 in the direction of the arrow 69, the extraction member 64 penetrates into the stick 8 of the material used at the edge of this stick and enters the side wall 12 of the cup. Penetrate) The product forming the stick 8 of material is soft enough to allow this penetration. The outer diameter of the extraction member 64 is substantially equal to or slightly smaller than the inner diameter of the side wall 12 apart from the ribs 14 and 66, so that the free end 65 of the extraction member 64 is free of the cup 7. It can penetrate into the end 13 without difficulty. Then, the inclined surface 15 and the inclined surface 67 cooperate with each other while elastically deforming the extraction member 64 and the side wall 12 of the cup, so that the outer lip 66 of the extraction member 64 is the inner lip of the cup ( 14), and then the outer lip 66 of the extraction member hooks under the inner lip 14 of the cup and secures it in place as shown in more detail in FIG. 9A.

Then, the used cartridge 6 of the applicator 1 is firmly fixed to the extraction member 64, so that the user pulls the refill 41 in the direction of the arrow 70 from the sliding element 24 of the applicator. The used cartridge 6 can be removed (see FIG. 10). Thus, the used cartridge 6 is completely received in the extraction housing 63 of the refill 41 and the operation of extracting the used cartridge becomes easy and does not get smeared on the user.

If the user wants to install a new cartridge 6 of the refill 41 in the applicator 1, he opens the second end 46 of the refill housing 43 as shown in FIGS. 11 and 12. do.

To this end, the user thus raises the cap 54 by sliding the pivot 57 of this cup along the corresponding slit 59 in the refill casing 42 in the direction of the arrow 71 in FIG. 11.

The cap is then in the release position, allowing it to swing freely on the casing 42 as indicated by arrow 72 in FIG. If the second end 46 of the refill housing 43 is initially sealed by the membrane 48 described above, the user also knows that the refill housing 43 is made of the protective tube 2 of the applicator 1. The refill 41 is directed to face the two ends 4.

As shown in FIG. 13, the user then inserts the protective tube 2 of the applicator into the refill housing 43 of the refill, the inner diameter of which is the outer diameter of the ferrule 5 of the protective tube 2. Since the passage is substantially the same (or the same as the outer diameter of the protective tube 2 when the ferrule 5 is omitted), the central axis X 'of the refill is in the direction of the arrow 73 where the refill 41 is shown in FIG. When aligned with the protective tube (2) is aligned with the central axis (X) of the applicator. In addition, since the outer diameter of the annular wall 50 of the refill housing can be substantially the same as the inner diameter of the protective tube 2, it can be inserted into the protective tube 2 during this movement, contributing to guiding the refill 41. do. It is particularly preferred to have a centering means between the ferrule 5 in preparation for hooking the lower part of the refill device 43 and the used refill.

The user then moves in the direction of the arrow 73 until the elastic lug 35 of the cup 7 of the new refill 6 is engaged with the central opening 34 of the sliding element 24 which is part of the applicator 1. Press the casing 42 of the refill 41 or reposition along the axis XX 'and then press the cap. It can be clearly seen that this snapping into place is fastened in place to the user by the characteristic click noise emitted by the elastic lug 35. The user then pulls the refill 41 in the direction opposite the arrow 73. The applicator 1 is then in the situation of FIGS. 2 and 3 with a new cartridge 6 of material.

The user preferably ensures that the cup with the used stick of material before each refilling step, in particular during the placement of a new cartridge of the product, is in the lowest possible position to limit the risk of damage to the applicator during the hooking process. The same is true for a new stick of material during the last step of removing the refill.

The second and third embodiments of the present invention shown in FIGS. 14-20A have many points in common in the first embodiment of the present invention, and therefore will not be described as a whole below. Only the differences in these second and third embodiments of the present invention are described in detail with respect to the first embodiment described above, and it is understood that the advantages already described for the first embodiment are retained in the second embodiment as well. .

B. Second of the Invention Example

In a second embodiment of the invention, the applicator 1 is characterized in that the inner lip 114 of the cup 7 has a thread on the inner surface of the side wall 12 of the cup as can be seen in FIGS. 14 and 15. Only the fact that it is in form is different from the first embodiment of the present invention. In addition, the outer lip 166 of the extraction member 64 of the refill may also be in the form of an external thread formed to be screwed into the inner threading of the cup 7 of the cosmetic cartridge (see FIG. 15).

Therefore, as shown in Figs. 16 and 16A, the extraction housing of the refill 41 to retract the protective tube 2 of the applicator during the operation of dismounting the used cartridge 6 from the applicator 1; 62 is first applied in the direction of the arrow 69, and then the user causes the thread 166 of the extraction member 64 to penetrate the extraction member into the stick 8 of the material, as shown in FIGS. 16 and 16A. The refill 41 is rotated along the central axis X 'in the direction of screwing into the inner thread 114 of the cup 7 of the cartridge used.

The used cartridge 6 can then be pulled out of the applicator 1 by pulling in the opposite direction to the arrow 69 in the manner as described above for the first embodiment of the present invention, and the refill housing 43 The new cartridge 6 housed in can be placed in the applicator 1 by simply inserting it in the direction of the arrow 73 in the same manner as in the first embodiment of the present invention (see Fig. 17).

C. Third of the present invention Example

In the third embodiment of the present invention, as shown in Figs. 18 and 19, the cartridge 6 of the material is the cartridge of the first embodiment due to the fact that the side wall 12 of the cup of this cartridge is no longer internal. Is distinguished from. However, the edge 11 of this cup has a central opening 274 bounding an inner lip 214 consisting of a lower end 11 surrounding the central opening 274 at the center of the elastic lug 235. The inner lip 214 is covered by the material 8 inside the cup as in another embodiment of the present invention.

This elastic lug 235 advantageously has a diameter larger than the diameter of the elastic lug 35 of the first embodiment, the elastic lug 235 for example providing the elastic lug 235 with the sliding element 24 of the applicator. It has a sidewall 236 that forms a cylinder along axis X with an outer lip 237 at the free end to snap to the central opening 274 of (see FIG. 18). If desired, this central opening 274 can be larger than the central opening 34 of the first embodiment of the present invention, and the screw 223 of the applicator has two flat sidewalls similar to the sidewall 26 of the first embodiment. Due to the fact that 226 is more different from the flat sidewall 26 in the first embodiment of the present invention, it may be different from the screw 23 of the first embodiment.

The opening 230 in the lateral wall 31 is formed to match the shape of the side wall 226 described above.
